| 摘要: |
| 基于爆破法扫雷爆破筒扫雷作用原理,设计了8.2 kg一次引爆型固态FAE扫雷装置。通过改变起爆位置和设置方式,多次野外近地面爆炸试验,采用反射压力传感器在装药正向与侧向离爆点不同位置进行压力测试,同时在正向测线压力传感器的对应位置设置某型防步兵地雷,得到爆炸场不同位置处的爆炸参数以及防步兵雷扫雷范围。结果表明:水平设置扫雷装药的扫雷范围明显大于垂直设置的装药,最佳炸高约为0.60 m；且其爆炸场正压区作用时间曲线呈“V”形,产物作用范围达63倍装药半径,与等当量的TNT的作用时间有明显的优势；本装置的扫雷范围约为目前扫雷爆破筒爆破扫雷范围的1.8～3.85倍,正向可靠扫雷范围可达其装药半径的77倍,侧向达69倍。由于该装药爆炸作用区域正压作用时间明显加长,因此有利于各种地雷的清除,是一种潜在高效的爆破法扫雷装药。 |

| Abstract: |
| Based on the principle of the function of mine clearance by the way of blasting tube, the 8.2 kg solid-state FAE(fuel air explosive) mine clearance device was designed. By changing the initial explosive position and the method of setting up, in the multiple field near ground explosion tests, the stress tests were conducted by adopting reflection pressure sensor to test forward and lateral pressure from different explosive locations, at the same time a certain type of anti-infantry mines in the corresponding burst position of the forward line pressure sensor was set, and the explosive parameters in different location′s explosive field and the scope of anti-infantry′s mines clearance was obtained. Results show that the clearance range of the horizontal charge was significantly larger than that of the vertical charge, and the optimal blast height was about 0.60 m. Moreover, the acting time curve of the positive pressure zone of the explosion field is of “V” type, and the acting range of the product is up to 63 times of the charging radius, which has obvious advantages over the acting time of equivalent TNT. The mine clearance range of this device is about 1.8~3.85 times of the current mine clearance range of blasting tube blasting, the forward reliable mine clearance range can be 77 times of the charging radius, and the side can be 69 times. Since the positive pressure action time of the explosive zone is significantly longer, so it is beneficial to the clearance of all kinds of mines, and it is a potentially efficient humanitarian mine-clearing charge. |
